Breakpoints don't work on cppia compiled with HXCPP_DEBUGGER

Right now, when running a debugger session compiled with HXCPP_DEBUGGER, the cppia host can still accept breakpoints, but anything that is running on cppia side ignores them. It seems however that it is possible to inspect a cppia stack frame - and see e.g. calling parameters. But neither local variables nor inspecting a value with more than one depth is supported on a cppia stack frame
